I'd say unless you know they will be up (you've dealt with them before) or they specify that they will be up and it's ok to call, then call. Any thing else, no. I wouldn't call.
My mindset is of that that if something is important enough for the customer to call in late at night and not just wait until the morning to call, they would have no issues with someone calling them back within 30 minutes. 15 minutes. Hell, even 5 minutes.
